Well, 500hp is kind of risky, but it will probably hold up.
Hypereutectic pistons are a type of casting. All pistons are either forged or cast. The cast pistons are broken down into three categories, hypo-eutectic (low silicone content), eutectic (medium silicone content), and hyper-eutectic(high silicone content). The more silicone you use, the stronger the piston becomes, but at the same time, they become more brittle. Forged pistons are heavier, but they flex more with heat. Hyper-eutectics can be physically just as strong as forged pistons, but once the heat gets too high, they shatter before they melt. Some of you might remember Keith Black pistons. Keith Black was an engine builder who specialized in selling his own brand of hyper-eutectic pistons. He was of the opinion that a hyper-eutectic piston made a better performance piston than a forged one.
When you use the term BOP, you have to be more specific. All the BOP transmissions are identical, but when you are referring to the engine, you have to brand specific, because the engines are totally different for different manufacturers.
